Singlespeed & Fixed Gear"I still feel that variable gears are only for people over forty-five.
Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Keio velodrome is easiest to get to. They have racing on the 25th, 26th and 27th (Wed - Fri). One thing I can't work out is, the racing starts at 2pm (10am on 27th), but they're calling the races "nighter" or night meetings. Maybe there's more than one session per day?
